1. Around 11,000 years ago the environment changed dramatically. Glaciers had retreated across the great lakes but the climate suddenly got much colder and drier. Because of the change in climate and a gradual increase in population, humans changed their way of life. Archaeologists call this a cultural Clovis points Fluted points adaptation cervid flute lithic nomadic rivers seasonal round settlement pattern .
2. To improve their hunting success the Paleoindian people invented new weapons for hunting animals. Clovis points Fluted points adaptation cervid flute lithic nomadic rivers seasonal round settlement pattern are spear points, which are longer than they are wide, and are thinner in the area away from the point.
3. The thinning is called a Clovis points Fluted points adaptation cervid flute lithic nomadic rivers seasonal round settlement pattern .
4. The oldest of these fluted points are called Clovis points Fluted points adaptation cervid flute lithic nomadic rivers seasonal round settlement pattern , named after a site in New Mexico where they were first found.
5. Archaeologists have found evidence of blood residue on stone tools at the Shoop site in Dauphin County, Pennsylvania. This blood residue is Clovis points Fluted points adaptation cervid flute lithic nomadic rivers seasonal round settlement pattern blood or blood from deer, elk, moose and caribou.
6. Many Paleoindian sites in Pennsylvania are found near Clovis points Fluted points adaptation cervid flute lithic nomadic rivers seasonal round settlement pattern , probably because they provided water to drink, transportation, and a habitat for animals and plants. Because these sites have little evidence, archaeologists can only guess at the importance of this type of location to these people.
7. But stone tools provide evidence that the Paleoindian people were Clovis points Fluted points adaptation cervid flute lithic nomadic rivers seasonal round settlement pattern . They appear to have traveled annually to places where the best quality Clovis points Fluted points adaptation cervid flute lithic nomadic rivers seasonal round settlement pattern material was abundant, in stone quarries near Allentown, in northern Virginia and in Delaware.
8. Archaeologists refer to yearly trips to find resources as a Clovis points Fluted points adaptation cervid flute lithic nomadic rivers seasonal round settlement pattern and the way people move and settle over the landscape as a Clovis points Fluted points adaptation cervid flute lithic nomadic rivers seasonal round settlement pattern .
